DALLAS — Dallas police say a man and a woman have been found shot to death inside a minivan in a drug-related investigation.

Police identified the man as 36-year-old Oscar Castillo of Houston. The name of the 42-year-old Dallas woman was not immediately released, pending notification of relatives.
